My observation the past few years of the social side of the girl in her teens, and especially the girl who has left school, has made me feel that if the opportunity to choose came to me as to Solomon, I would rather have the knowledge and power to give the young people of to-day sane, safe amusement than anything else I know. The social side of the girl reveals itself not only in the desire to have a good time, but in the deep and ardent friendships formed during the teen period. While she enjoys to the full the society of the group, the girl in her teens invariably has a “dearest friend,” who shares her joys, sorrows and confidences. This tendency becomes especially evident at sixteen and becomes more marked at the latter part of the period. These friendships may be the source of greatest blessings or may mean the lowering of the whole tone of moral life. Both mother and teacher need to observe carefully the formation of friendships and be sure to encourage only the helpful ones. Public school teachers of experience can all testify to the rapid changes in girls which so often follow the development of a deep friendship. I remember a girl of sixteen, dreamy, imaginative, and so much interested in her boy companions that lessons, home interests, and everything else were sacrificed. What to do with her, and what interests to substitute, were questions that both mother and teacher failed to solve. At a most opportune time a “new girl” moved into the neighborhood and entered school. She was practical, attractive, a good scholar, greatly interested in outdoor athletics. Because they were neighbors, the two girls were thrown much together. The companionship deepened into friendship. Soon the dreamy sixteen-year-old was playing tennis on summer afternoons, and reading aloud in the hammock afterward to rest. When winter came she suddenly decided that school and study were worth while, brought up all her averages, and made up her mind to try for college. Skating and the gymnasium made her a new girl. And all this transformation, fortunately for her good, came naturally and very rapidly through the influence of her companion. It comes almost as quickly in the other direction. Nothing can be more helpful to the shy, timid, self-conscious girl than the companionship of one who will encourage her and help her take her place with others in the social life of which she is a part.
